大家好，我在使用winhttp编程的时候碰到2个问题，主要是Ntlm代理环境下访问网络方面的问题，百思不得其解，向大家请教：

1.以下这份代码，在xp-Ntlm代理环境下，运行很正常，但是到了win7下，服务器始终返回407.
抓包发现：
在XP:WinhttpSendRequest后，程序开始发包，但是不会自动进行NTLM的验证过程，验证过程需要自己实现（HASH和挑战-响应过程不需要代码实现，程序自动进行），需要自己resend。
具体过程为：
1) Get www.xxx.com
2) Get NtlmSSP_NEGOTIATE
3) Get NtlmSSP_AUTH
然后服务器就返回200.

在win7：WinhttpSendRequest后，程序开始发包，连续进行了3次发包，验证过程已经一次性地发出去了，过程为
1) Get www.xxx.com
2) Get NtlmSSP_NEGOTIATE
3) Get NtlmSSP_AUTH
然后服务器就返回407.再继续resend多少次都是407.win7下浏览器设置代理后可以正常上网。

问题：win7下程序进行NTLM验证需要什么特别的设置吗？

2.winhttp中如果收到302会自动重定向，有没有办法使得程序不会自动重定向？
（在C#中有这个设置,c++中目前我还没找到方法）

希望大家能指点一二，只能发100分帖，解决问题了，会补上。

马勒戈壁的，今天再次被此问题困扰…… 原因如下：因为SQUID代理服务器不支持HTTP1.1请求，而WinHttp会默认使用HTTP/1.1，导致失败。解决方案：1.WinhttpOpenRequest使用HTTP/1.0访问 2.Squid打开对http/1.1的支持经测试第2步可以解决。坑爹！（但是ntlm+http/1.0支持的代理是否仍会出问题，这点有待测试）
